Cover
A Cooler Extreme fabric cover with cool-touch properties, which means the surface feels noticeably cooler when you first lie down. It works by dispersing heat away from your body through the night.
StayCool gel
Pressure-sensitive StayCool gel that creates a supportive, edge to edge floating sensation. It also reduces heat build-up, so warm sleepers should feel a genuine difference.
Pocket springs and Softech springs
Pocketed and Softech springs deliver body-cushioning comfort, with 1,800 springs in the king size. Each spring moves independently, which means support that follows your shape rather than pushing back as one unit.
Superbond foam
Superbond foam forms part of the filling system, adding a stable comfort layer beneath the springs and gel.

Key benefits
- Cooling where you lie closest: At 67.5cm each you'll sleep nearer your partner than on a UK king, and the cool-touch cover disperses that shared warmth rather than letting it build up.
- Fits a typical bedroom: We suggest a room of at least 2.6m x 2.8m, which means most main bedrooms and plenty of second bedrooms can take this mattress with space to walk round it.
- Space for bedside tables: Allow around 3m x 3m and you can usually keep a bedside table on each side, so neither of you has to reach across the other at night.
- Less disturbance on a shared width: The pocket and Softech springs move independently, which means a partner turning over is less likely to jolt you when you're sharing 135cm of width.
- Easy to dress: Double sheets are sold almost everywhere and a 200 x 200cm double duvet fits, so kitting out the bed takes no special hunting.
This size suits you if...
You share the bed with a partner in a bedroom of ordinary UK proportions, one or both of you tends to wake up too warm, or you're furnishing a guest room where visiting couples stay a night or two.
Consider another size if...
You're both tall, broad-shouldered or restless sleepers who already feel cramped at 67.5cm each. We'd recommend the UK king instead, which gives 75cm each and is 10cm longer; allow at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Cooler Extreme 1800 UK double cool enough for two people?
The cooling layers are the same in every size, but on a UK double you lie closer together, with 67.5cm each. That's where a cool-touch cover and StayCool gel help most, since the warmth two people give off has less room to spread out than on a wider bed.
Will a Sleepeezee Cooler Extreme 1800 UK double fit in my bedroom?
We suggest at least 2.6m x 2.8m for this mattress in a UK double, and around 3m x 3m if you want bedside tables on both sides and space to open a wardrobe. Measure the room before ordering, including where doors and radiators sit.
What size is a Sleepeezee Cooler Extreme 1800 UK double in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That's the standard UK double, so it should fit a UK double bed frame or divan base made to the same size.
How much extra room does the Sleepeezee Cooler Extreme 1800 king give over the double?
The UK king is 15cm wider and 10cm longer than the UK double, giving 75cm each rather than 67.5cm, so the UK double gives 7.5cm less each. The trade-off is floor space: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Is a Sleepeezee Cooler Extreme 1800 UK double wide enough for me and a pet?
For one sleeper, a UK double gives 135cm of width, which leaves room for a dog or cat curled up in a corner. With two people plus a pet it gets tight at 67.5cm each. If that's your household, the UK king adds 15cm of width.
